METAL POLE.

original No. 1,817,262, dated February 8, 1927, Serial No.' 130,285, med Augnlt 1,9, 1938. Application for vreissue filed J'ufne M1927. Serial lo. 196,133.

My vlinventionrelates to an improved construction of metal poles or posts forjuse 1n the construction of telephone and telegraphlines, fence construction, and for anyother I purposes for which such poles may be found appropriate, whereby such a pole or post 1s lprovided of a minimum weight and maximum carrying strength, and also one that will be durable and substantially permanent l0 in use, and by the use of which the disadvantages experienced in the use of wooden:

` Figure 4, a detail view of other forms of angle irons that may be employed.

, In the accompanying drawings a pole or post of my improved construction is shown kconstructed of a series of members of strands d in cross-section, a portion of which vexten \in a spiral direction lengthwise of the pole and another portion extend lengthlwise of the pole in a spiral direction re- Y verse to that of the first portion.

In theI drawings the outside members 5 Aare formed into a left-hand spiral and the inner members 6 are formed into a rightnhand spiral, there being seven` members extending in each direction and crossing each 40 other at intervals throughout the length of the pole. The flat faces of the inner members and outer members bear against each other at the crossingpoints, as' shown most clearly at the top of Figure 2, at which points the members are secured together by any ap roved method but preferably by elec tric we ding, although riveting or any other approved method may be employed if desired. 5 At theextreme bottom of the post or pole is a wide strong metal band 7 to which the lower ends of the members 5 and 6 are se- .which itis to be put, and a so that the members 5 and 6 are of appropriate size tomake a post or 4pole of the strength and rigidity desiredl for any special purpose.

By reason of the special form of the memy bers 5 and 6 secured together in a spiral form as shofvn, a`pole with a comparatively small amount of metal is provided capable of carrying a comparatively reat strain, the angles of the members being so positioned that each member supplements the and rigidity to the structure.

A similar band 9 is placed at the top o the le to which the upper ends of the mem ers 5 and 6 are secured in the same manner as indicated inrespect to the bands 7 and 8.

In Figure 4 I have shown other forms of members an ular in cross-Section which may be used in ieu of the form vshown in the principal figures, if desired.

It will be obvious to those skilled in the art that the posts formingy the subjectmatter of this invention may be made of any length or size desired to adapt them for any particular use or purpose and that such modifications as permited by the scope of the claims may be made without departing from other in resisting strain and lending strength the spirit of `my invention.

Having thus fully described my said invention, what I claim as vnew and desire to secure by Let-ters Patent, is:

1. A post of the class described formed of two groups of continuous bars of angle iron, one group wound right-hand and the other group wound left-hand, the faces of parallel with the corresponding faces of the other group and the bars of the two'groups being secured together at crossing points, substantialy as set forth.

2. A post of the class described composedof an outer group of continuous bars of angle iron spirally wound in one direction, an inner group of continuous bars of angle iron spirally wound in the reverse direction, bands positioned between said outer and inner groups, the adjacent faces of the bars of the respective groups being adapted to rest against the outer and inner Ifaces respectivel of said bands, and means for securing t e bars of said respective groups and said bands together, substantially as set forth.

3. A post of the class described comprising members angular in cross section extending in a spiral direction lengthwise of the post part of said members in one direction and part in the reverse direction, the angles of the members extending in one direction being substantialy parallel with the angles of the members extending in the reverse direction, said members being secured together at their crossing points, substantially as set forth.

4. A pole formed of two groups of con-r tinuous members, the members of one .group extending around the pole in a direction opposite the members of the other group, one or more of said members having a rib disposed substantially at right angles to the surface of the pole, substantially as set forth.

5. A pole or post formed of two groups of continuous members, the members of one group extending longitudinally of the pole .at an angle to the members of the other group, certain of said members having up-V standing ribs disposed substantially at right angles to the surface of the pole, substantially as set forth.

6. A pole formed of two groups of spirally 3wound continuous members, lthe members of one group being Wound .in a direction opposite to the members of the otherv group, each member having an outwardly directed rib substantially at right angles to the surface of the pole, substantially as set forth.

7. A pole or post comprising -two groups of continuous members forming a hollow network structure, the membersconstituting one group extending longitudinally of the pole across the members of the other group, one 'or more of said members having a longitudinally extending strengthening rib on its back, substantially as set forth.

In witness whereof, I hereunto set my hand at the city ofWashington, D. C., this 2nd day of June, 1927. l
